"UNIX Environment Advanced Programming" development environment Configuration: Apue.h header file __ Programming

"UNIX Environment Advanced Programming" has a lot of code in the process of learning, you need to actually write these code, debugging run. The author refers to the #include "apue.h" in the dock file, which contains the common header files and some custom functions, we have to be able to complete their configuration, the test machine in this paper is ubuntu16.04.

1, first download its source code:src.3e.tar.gz in http://www.apuebook.com/

2, decompression TAR-XVF src.3e.tar.gz

3, into the apue.3e,

$ > CD apue.3e

$ > Make

4, this time may be an error, can not find-lbsd, the solution:

$>sudo Apt-get Install Libbsd-dev

5, make again, then copy include/apue.h to/usr/include/folder, Lib/libapue.a copy to/usr/local/lib/directory

sudo cp include/apue.h/usr/include/

SUDP CP Lib/libapue.a/usr/local/lib

6, use GCC to compile, take the first example in the book as an example:

7, or use another method, or copy the Apue.3e/lib/error.c file to the/usr/include/below, and then modify the Apue.h file.

Then add a line to the back (at least after max_line), #include "error.c"
